IMPROVED EVAPQRATOR FOR SUGAR, AND OTHER LIQUIDE Thg Schedule referred to in ythese Letters Patent and making part' of the lame.

To all whom it may concern Be it known that we, THOMAS SCANTLIN and J AMES M. SCANTLIN, of Evansville, in the county of Vanderburg, and State of Indiana, have invented a new and improved Evaporator; and we do hereby declarethat the following is a full, clear, and exact description thereof, whichpwill enable others skilled in the art to make and use 'the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1 represents a vertical longitudinal' section of our improved evaporator.

Figure 2 is a vertical transverse sectioniof `the sam'e.

Figure 3 is a detail horizontal section of the same, taken on the plane of the line x-x, g. l.

Similar letters of reference indicate corresponding parts.

This invention relates to certain improvements in sugar-cane and other evaporators, and has for its object to produce simple action, and perfectly satisfactory operation.

The invention consists, first, in the use of open connecting-channels, which unite the diierent chambers of the pan, on the outside of the said pan, so that they will he out of the way, and in arranging the gates within said outside channels; also, in arranging longitudinal draught-passages under the pan; and, finally,

in the combination ci: an ash-pit, with a portable furnace, for the purpose of regulating the heat.

A, in the drawing, represents an evaporating-pan, of suitable form and combination, divided by means of vertical partitions, c a, into a suitable number of conipartments, b b, and supported ona furnace, B.

The furnace B has an inclined upper edge to support the fan in 'an inclined position, and is made of nearly semi-cylindrical form.

The ash-pit c is arrangedunder the grate d, which is in line with the bottom of the cylinder.

The draught-door c ot' the ash-pit has a pivoted catch, f, which can be locked in one of a series of notches, that is provided in a curved bar, g, prcjecting from the front of the furnace, as shown in fig. 3. The proper degree of draught can thus beobtained, and the door so locked as to retain it.

The various compartments b of the pan are connected with each other by means of boxes, C C, that are' attached to the sides ofthe pan, as shown.

Each box O h as two openings, h h, leading into two adjoining compartments b.

A gate, li, is arranged in. each box C, to close the apertures h.

By thus having the connections and gates outside of the pau, the latter can be more readily kept clean and in repair.

On -the upper longitudinal edges of the furnace are arranged inward-projecting flanges, jj, which produce air-passages, k It, of which the ends are open, by having the ends of the furnace perforated, as shown. By these passages theupper part of the furnace is cooled, and prevent-ed from burning.

Having thus described our invention,

What we claim as new, and desire to secure by Letters Patent, is

l. The open boxes C C, arranged on the outside of the pan, to connect with the compartments of thev same, substantially as herein shown and described.

2. The gates i, arranged in the boxes C, on the outside of the evaporating-pan, substantially as herein shown and described.

The ash-pit, in combination with a portable furnace, for the purpose oi' regulating the heat, as set forth. 7

4. The flanges j j, formed on the upper edges of the furnace, to produce open air-passages k It, for cooling the upper part of the furnace, substantially as herein shown and described.
